New Product Launch: Empress™ EM02-ETH

The new member of the Empress Reader family is finally here! EM02-ETH is the latest product addition to the Empress™ Reader family, which is equipped with improved designs and additional functionalities.

Designed to be more stylish and user-friendly, the panel is repositioned on the top for more convenient operation. Plastic casing, which is light, durable and easy for mounting onto different locations, is adopted to replace the original metal case. At the same time, the EM02-ETH reader provides more powerful functionalities with enhanced performance.

There are several featured upgrades and functionalities of EM02-ETH. First, the new RSSI function provides signal strength data for assessing distance and more accurate tag location. Second, with the improved reading speed, the EM02-ETH reader is capable of reading around 150 tags per second, significantly enhancing efficiency. Third, remote firmware upgrade is supported allowing users to update the reader’s firmware conveniently.

Together with the launch of EM02-ETH, catalogue and introduction video has also been published. Please click on the following links to download the product catalogue and watch the video.

Final Testing of Empress™ EM02-ETH

It is important to ensure quality and performance of new product before launching. Hong Kong RFID introduces the new Empress™ Reader – EM02-ETH after a thorough product research and development, design and fine-tuning with multiple testing to ensure sure good quality and stable performance.

The testing video shows how the engineer of Hong Kong RFID conducts testing of the accuracy of EM02-ETH reader’s frequency. Testing was carried out in our world-class laboratory for RF and wireless testing. This test lab is equipped with a shielding room that blocks all external RF signals to provide RF-free environment for testing. The shielding room is of international standard and accuracy for the test is ensured.

The equipment used by the engineer is also of international standard. EM02-ETH is connected to a network analyzer to analyze the stability of the frequency produced by the reader. Such analyzing and testing conducted in a shielding room is guaranteed to achieve highest accuracy as no interference from outside could affect the test.

Comparison between Active and Passive RFID

Curious on the differences between active and passive RFID? How much do you know about the difference between their characteristics and functionalities? Watch the comparison video that demonstrates the differences between active and passive tag in various real-life applications on our YouTube channel to find out the answer now!

RFID products are mainly divided into two categories: Active and Passive. Though they both adopt RFID technology, their functionalities are completely different and have distinct characteristics and capabilities. The most obvious difference is that active RFID tags have their own power source allowing the tag to continuously send signals to the reader, whereas passive RFID tags have to rely on the RF energy sent from the reader to give a signal. With this distinctive difference, active RFID products can be applied to wider range of applications and more convenience can be provided to users.

Tracking can only be performed by active tag because only active tags can actively send out signals periodically to the reader at a longer distance. Passive tags are required to be tapped against the reader for reading which could not possibly facilitate tracking functions. Digital sensors can be added to active tags to perform environmental control, such as monitoring the temperature and relative humidity of server rooms. Passive tags which are only a simple, flat circuit could not accommodate such sophisticated feature.

In some applications, both active and passive tags can perform the task, but active tags can perform the task in a better way. For example, in access control and customer relationship management, passive tag users have to take out the tag for the reader read, while active tag users can skip this process as the reading distance for active tags is much longer and reading of tags is not affected by water and metal.

Environment Control System for Museums

In museums and art centres, valuable paintings, art pieces and historic artifacts are stored for showcase to the public. These exhibits require delicate care and well-controlled environment to ensure good preservation. Managing the museum environment is thus a vital task. Apart from the material of the exhibit, the number of visitors, the weather and air conditioning are all factors affecting the relative humidity and temperature of the museum.

To closely monitor the humidity and temperature levels in the museum, staff is required to measure the temperature and relative humidity from time to time in order to adjust the ventilation and air-conditioning systems accordingly. This result in high time cost in measuring the parameters frequently, varying accuracy rate due to manual operation and high operation cost.

Our Tempcorder™ Moist Tag is used to perform the measuring task automatically and more accurately. Moist Tags are placed in different locations for capturing temperature and humidity data. Equipped with an accurate digital humidity sensor of up to 1% resolution and wireless functions, Tempcorder™ Moist Tag can measure humidity range from 0 - 100%  and  temperature from -25°C to +80°C. The humidity and temperature data is sent along with the tag ID to the reader and then to the central server periodically, to prevent damages on the exhibits due to environment changes.
